or ONE-HALF SPRING BED-BOTTOM.

No. 857,324. Specification of Letters Patent. Patented June 18, 1907.

Application filed January 23,1906. Serial No. 297,503.

To all whom, it may concern:

Be it known that I, CHARLEs D. BROU- YETTE, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Spring Bed-Bottoms, of which the the wires of the crossed-wire fabric to the end coils of the springs, andFig. 4 is a sectional detail view taken in the plane indicated by line bb in Fig. 1 and showing certain features of the means for supporting the outersides of the end coils of the springs of the outer rows or series in the structure from the border-wire or reinforcingframe of the crossed-wire fabric.

As shown in these views, the improved spring-structure is embodied in a s ring bedbottom of a well-known type w ierein are provided helical springs 1, 1, having closed end coils 2, 2, which are interlocked as will be hereinafter explained with a crossed-wire fabric comprising a border-wire or reinforcaa in Fig. 1 and showing the relations of This invention relates to certain improvements in that class of spring-structures commonly employed for bed-bottoms, seats and the like wherein are comprised helical springs having end coils'with which is connected a wire-fabric formed of intersecting wires interlocked with each other and with such end coils in such a manner as-to afford means for retaining the springs in proper relative position, the wire-fabric being at the same time ing-frame 3 of suitable strength and extendadapted toserve as a support for the bedding ed along the edges or sides of the bed-botor upholstery, and the object of the invention tom, said fabric also comprising main, auxiland convenient manner.

is to provide a structure of this general character of a simple and comparatively inexpensive nature and of a compact, strong and durable construction wherein the intersecting wires are so formed and connected with the end coils of said springs as to afford a maximum of strength and. rigidity in the structure while being capable of being assembled, in the manufacture of the improved structure, in a rapid iary and lateral tie-wires 4, 5 and 7 which are extended in one direction across the top of the bed-bottom arallel with each other and have their ends ent around the border-wire or reinforcing-frame 3 as seen at '6, 6, while their intermediate portions are provided with means for engaging-connectionwith the end coils 2, 2 of the springs, the arrangement being such that one of the tie-wires traverses one side of the end coil of each spring in the row traversed by such tie-wire, there being, by this arrangement two tie-wires extended along opposite sides of the end coils of the springs of each row or series in the structure. The crossed-wire fabric also comprises transversely-extended looking or retaining wires 8, 8 which are extended at right-angles to the tie-wires and intersect therewith, passing centrally across the end coils of the several springs in the respective transverse rows or series, the ends of said transverse looking or retaining wires being provided with loops or eyes 9, 9 bent in them border-wire or frame 3 of the fabric in such 1 manner as to effectively hold the said transverse wires in position, the intermediate portions of said transverse wires 8, 8 being interlocked, as will be hereinafter explained with the tie-wires andwith the end coils of the springs in such a way as to lock and hold said arts securely in relation.

The arrangement of the tie-wires is such that each such wire is passed beneath one side of the end coil of each spring 1 in the The invention consists in certain novel features of the construction and combinations and arrangements of the several parts of the improved.spring-structure, whereby certain important advantages are attained and the device is made simpler, cheaper and otherwise better adapted and more convenient for use in bed-bottoms, seats, and the like, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings which serve to illustrate the invention-Figure 1 is a fragmentary plan view showing one corner portion of a spring bed-bottom embodying my improvements; Fig. 2 is a fragmentary perspective view showing a portion of one of the tie-wires of the crossed-wire fabric of the spring-structure and showing certain details of the relation thereof to the end coil of one of the springs; Fig. 3 is a fragmentary sectional view taken vertically through the structure in the plane indicated by the line l and encircling the til row or series traversed by such tie -wire, whereby said tie-wire is engaged for supporting-connection at two oints 10, 10, beneath each such end-coil, an since each row or series of springs is traversed by two of the tiewires, extended along opposite sides of the end coils of its springs, it will be apparent that the tie-wires are so engaged for supporting connection with each end coil 2 at four points 10, 10, which will be distributed around the circumference of the end coil at suitable distances apart. The main and auxiliary tie-wires 4 and 5 are, by preference and as herein shown, extended in a general plane above the end coils of the s rings 1, so that the bedding may ordinarily e sup orted out of contact with said end coils, an the main tie wires are rovided at suitable points with downward y-bent portions 11, 11 which are extended beneath the parts 10, 10 of the end coils which have supporting-connection therewith, the parts of said main tiewire between said downwardly-bent portions 11 being extended across above the end coils so as to interlock therewith as shown in Figs. 1 and 2. The auxiliary tie-wires 5 also have downwardly-bent portions 12, 12 which are passed beneath the portions 10, 10, of the end coils with which they are designed for sup orting connection, and are provided witi upwardly-extended parts 15, 15, intermediate between said downwardly-bent parts 12, 12, the said u wardly-ex'tended portions 15 being designecF to extend above the end coils 2 of the springs traversed by such auxiliary tie-wires at points intermediate between those points 10, 10, at which said tie-wire is engaged for supporting-connection beneath said end coils 2. The lateral tie-wires 7 are extended along the edges or lateral sides of the bed-bottom adjacent to the border-wire or frame 3, and serve for connecting the outer sides of the end coils of the s rings of the outer rows or series with the said borderwire or frame 3 in order to hold the parts of the structure in relation and said lateral tiewires are also adapted for engagement at two points, 13, 13, beneath the end coils of the respective springs so that supporting-connection is thereby afforded with each such end coil at two points 10, 10. In this way it will be seen that each side of each end coil 2 is supported at two separated points 10, 10, upon one or another of the res ective tiewires 4, 5, and 7, and in assemb ing the improved spring-structure, the looking or retaining wires 8 are very readily engaged with opposite sides of the respective end coils so as to intersect saidoppositesides of the end coils at points midway between the oints 10, 10, whereat such sides of the end coils are supported upon the respective tie-wires.

As above stated, the lateral tie-wires 7, are arranged only along the lateral sides or edges of the bed-bottom, and have engagement only with the outer sides of the end coils of the outer lateral or edge rows or series of springs adjacent to the border-wire or frame 3 of the crossed-wire fabric, and at the intermediate portion of the bed-bottom, between said lateral tie-wires 7,- the main and auxiliary tie-wires 4 and 5 are grouped in pairs, as shown in Fig. 1, so that a main tie- Wire 4 is extended along one side of each end coil in one series or row of springs, while an auxiliary tie-wire 5 is extended along the adj acent sides of the end coils of the row or series of springs next adjacent. In this way the end coils in each row or series of springs will be traversed along one side by a main tie-wire 4 and along the other side by an auxiliary tie-wire 5, as will be readily understood.

The main tie-wires 4 are provided, at points intermediate between those portions 11, 11, which are engaged for supporting-connection beneath the ortions 10, 10, of the respective end coils, with laterally-directed elongated loops or arms 14, which are directed beneath the respective end coils and away from the same toward the end coils of the springs of the adjacent row or series, at the side thereof traversed by the corresponding auxiliary tiewire 5, said 100 s or arms 14 having their members located at opposite sides of the respective locking or retaining wires 8, 8 and being passed at their extremities, above the sides of the end coils at locations equi-distant between the oints 10, 10, at which the respective end coi s have supporting-connection with the downwardly-bent portions 12, 12, of the auxiliary tie-wires 5. By this arrangement, the said arms or loops 14, 14 of the main tie-wires 4 are caused to extend, at their points of intersection with the end coils, in planes beneath the intermediate upwardlybent portions 15, 15 of the auxiliary tiewires 5, and at their ends, said arms or loops 14 have upwardly-bent extremities 16, forming arched and elevated sockets extended above said raised intermediate portions 15 of the auxiliary tie-wires as seen in Figs. 1, 2 and 3, said sockets being designed to be readily traversed by the locking-wires 8, which are thereby caused to lock and retain said parts 16 and 15 of the main and auxilary tie-wires in relation with each other and with the end coils of the springs. In this way it will be seen that the sides of the coils traversed by the auxiliary tie-wires are prevented from tilting, and as the sides ofthe coils-traversed by the main tie-wires 4 are also engaged beneath the locking or retaining wires 8 at points intermediate between the points 10, 10, whereat said coils are supported on the portions 11, 11 of the main tie-wires 4, it will also be understood that the coils are eflectually held from tilting at said sides also.

The lateral tie-wires 7 are also provided with arms or elongated loops 17, 17, similar to the loops or arms 14 of the main tie-wires is not likely to be brought to bear on the portions 1 0, 10, of the end coils beneath which coils of the springs traversed by it and extended-laterally from said end coils with exsaid lateral tie Wires 7 have supporting-entremities passed between the upper face of gagement as shown at 13, but the members the end coils ofthe adjacent row of springs of the loops or arms 17 of the lateral tieand the lower face of the upwardly bent por- 4 and also located at points between those wires are passed above the end coils and are tions of the auxiliary tie-wire which are directed away therefrom toward the borderpassed through and interlock with such end wire orframe 3of the crossed-wire fabric and coils, said extremities of the loops having have their extremities provided with narrow .vertically-bent terminal portions engaged bebights 18, with which the terminal loops or hooks 9 of the looking or retaining wires 8 are engaged as shown in Figs. 1 and 4 for holding said arms or loops 17 in relation to the borderwire or frame 3. The outer parts of the looking or retaining wires 8 are engaged 'be- 1 neath the end coils of the springs at points intermediate between those portions 10, 10 of said coils beneath which the parts 13 of the lateral tie-wires are engaged so as to interlock with said end coils between the points at which the members of the arms or loops 17 are engaged above such end coils, whereby the said end coils will be securely held to the border-wire or frame of the crossed-wire fabric and will thereby be held from displacement.

From the above description of my improvements it will be evident that the improvedspring-structure is of an extremely simple and inexpensive nature and is especially well adapted for employment in bedbottoms, seats and the like, since it permits of securely holding the springs against displacement and is at the same time capable of assemblage with a minimum of labor.
